This tool is equipped with an electric cord which has an equipment-grounding conductor and a grounding plug.
Safety (( MK-370EXp Saw ON )) WARNING To avoid the possibility of the appliance or plug receptacle getting wet, position the machine to one side of a wall mounted receptacle. This will prevent water from dripping into the receptacle or plug. A "drip loop," shown in the picture below, should be arranged by the user to properly position the power cord relative to the power source. Use the drip loop as a way to prevent GFCI and plug from getting wet.
Safety (( MK-370EXP Saw ON )) WARNING Use of undersized extension cords result in low voltage to the motor that can result in motor burnout and premature failure. MK Diamond warns that equipment returned to us showing signs of being run in a low voltage condition, through the use of undersized extension cords,will be repaired or replaced totally at the customer’s expense.

The diamond blade can be dressed using the MK Dressing Stick (part# 152792) and by following the steps below.
